Product Description

what's the brief introduction of Thermal mass flow meter ?

1.It is a true mass flowmeter that can conveniently and accurately measure gas-flow rate without temperature and pressure compensation, from which users can get gas mass flow or standard volume flow.

2.Large ratio of measuring range. It can measure gas with velocity of flow from 100Nm/s to 0.5Nm/s, and be used in gas leak hunting.

3.Good anti-seismic performance and long useful life. The converter doesn’t contain movable part and pressure sense part, so that the measuring accuracy will not be influenced by shaking.

4.Easy installation and maintenance. If possible, on line installations and maintenance are allowed. (See Safety Notice)

5.Digital design. The meter utilizes digital circuit measurement to assure accurate result and convenient maintenance.

6.Factory automation and integration can be achieved by using RS-485 or HART communication.

what's the main features of thermal mass flow controller ?

1) If installed outside, the meter should be covered by sky shade to avoid exposing to the sun and rain.

2) Do not install in sharp pounding situation.

3)Do not expose to dangerous environment heavily charged with corrosive gas.

4) Do not share power source with polluting equipment such as converter and welding machine, and power conditioner can be installed for converter if necessary.
